Matter enclosed in heavy brackets appears in the original patent butforms no part of this reissue specification;

This invention relates to a portable bed lamp, although it may be alsoused as a desk lamp, and the lamp is provided with a rotatable shutterso that the light can be deflected in the olireetion desired.

An object of our invention is to provide a. novel portable lamp withadjustable shutter, which is formed of a plurality of and is, therefore,simple in construction and. inexpensive to manufacture.

A feature of our invention is to provide a novel portable lamp withadjustable shutter, in the various parts serve more than one functionwhen assembled, thus provl .ing a lame which is easy to assemble andalso which requires a minimum number of parts.

Other objects, advantages and. features of in vention may appear fromthe accompanying drawing, the subjoined detailed description and theappended claims.

In the drawing:

Figure l a top plan view of our per table lamp.

Figure 2 is a sectional View taken on line 2-4 Figure 1.

Figure 3 is a pers oectii e view of the shutter.

Figure is a transverse sectional view of the louvered case alone.

Referrin more particularly to the drawing, our portable lamp consists ofa case I, formed of a single sheet of metal, and before the case is bentit is out by means of a die to term the louvers The strip or material ist; l bent to form a substantial rectangular boxd e struc ture, which isopen at both ends the louvered part of which is semi-cylindrical. Theone of the case is closed by the cap 3, the cap being attached to thecase by means of screws 3 or the like. other end of the case is closedby aring 5, this ring also being attached to by means of screws The ring*5 is formed with an enlarged c ntral hole therein at l, the purpose oiwhich will be further described.

A transverse wall fixedly mounted within the case i and is no ne ladjacent 3. The wall 8 is provided with a dricai recessed bearing 9, thepurpose of which will be further described.

A semi cylindrical shutter it is mounted in the case I, the end ii ofthe shutter being journaled in the bearing 3. The opposite end of theshutter is closed by a cupped end l2 and this conned end protrudesthrough the opening "i, that it be to rotate the shutter as desired bythe user. A socket t3 is fixedly mounted in the wall 3, and the lightbulb i l,

which is mounted. in the socket 13, extends into the shutter l3,substantially as shown in ure 2.

It will be evident from the foregoing description that the case i can beassembled from a strip of metal and bent into the seznhreotangular form,the cap 3 and the ring 5 are both stamped from metal strips and areattached to the case by means of screws. Before the cap and the ring areattached, the transverse wall E; is mounted in the'case by Welding orsoldering this wall in position. The shutter it} is then inserted intothis bearing in the Wall ii. The ring 5 is then slipped over the cuppedend 52 and, thereafter, the ring a and the cap 3 are attached to eachend of the case by means of the screws and 5.

While the instant invention has been shown and described herein in whatis conceived to be the most practical and preferred embodiment, it isrecognised that departures may be made there from within the scope ofthe iiwentioc-z, which is therefore not to be limited to the detailsdisclosed herein but is to be accorded the jail sece of the claims so asto embrace any alt equivalent ammmtas and articles.
